To a. whom it may concern.-

Be it known that 1, THOMAS ROWLAND JORDAN, engineer, a subject of the Queen of Great Britain, and a resident of London, England, have invented new and useful Improvements in Apparatus for Crushing or Pulverizing Ores and other Substances, (for which I have obtained a patent in the following countries: Great Britain, dated February 23, 1889, No. 3,298; France, dated December 16, 1889, No. 201,242; Belgium, dated November 15, 1889, N 0. 88,334; Cape of- Good Hope, dated October 30,1889, No. 101 Natal, dated Novemher 6, 1889; Victoria, dated October 30, 1889, No. 7,222; New South Vales, dated October 31, 1889, No. 1,801; South Australia, dated October 30, 1889, No. 1,447 Queensland, dated February 27, 1889, No. 881, and Transvaal, dated September 2, 1889,) of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to apparatus for crushing or pulverizing ores and other substances.

The main object of my said invention is to provide for the withdrawal of the crushed material from the pulverizer by means of a current or currents of air during the operation of the said pulverizer.

My improved pulverizer is particularly advantageous for the crushing of cement, artificial manure, quartz, and other substances in a dry state.

In the accompanying drawings 1 have shown how my said invention may be conveniently and advantageously carried into practice.

A is a receptacle or pan, which is provided with a circular crushing path or channel A, and is fixed upon a strong hollow or tubular shaft B, arranged to be rotated about an inclined axis. In this pan are placed heavy spherical mullers or balls O, which in the rotation of the pan A are caused by gravity to roll and revolve about their axes on the said crushing path or channel without moving around the axis of rotation of the said shaft.

The ore or other substance to be crushed is fed into the said receptacle or pan through a feed-aperture A and is subjected in the said pan to a powerful crushing or grinding action between the said mullers or balls and the crushing path of the said pan.

The hollow shaft B on which the crushingpan is mounted is supported at its lower end in a massive step or bearing D and at its upper end in a bearing E, held in position by a framing F of wood or other suitable material. B is a pulley, which is firmly keyed or otherwise secured upon the shaft B, and to which rotary motion is imparted from a steam-engine or other suitable motor by means of beltgearing or in any other convenient manner. The aforesaid mullers or balls O will by their vibration and by striking against each other very rapidlyand effectually crush or grind the material fed into the pan. The finely-reduced particles are removed or extracted from the apparatus by an air-blast, produced, preferably, by suction, the current being 1nduced by means of a suitable exhauster through the main shaft B. The upper end of the said shaft is for this purpose connected with the exhaust or suction pipe H by a suitable joint, which, while preventing leakage, will permit rotation of the said shaft. The passage B through the said shaft communicates at its lower end with the crushing path or interior of the pan by means of four or any other suitable number of channels J. The material being crushed is during the operation of the machine repeatedly thrown over in front of these channels by means of suitable scrapers or brushes arranged in any convenient manner for the purpose. The fine and light particles are drawn from the machine through the said channels J and passage B and are conveyed through the pipe H to any convenient chamber.

The crushing-pan is completely closed, with the exception of the central feed-aperture A around the shaft B, by a cover A It is evident that my present improvements are applicable to other forms of pulverizers wherein it is practicable to remove the crushed material through a hollow shaft on which the crushing-pan is mounted.

What I claim is 1. In a crushing or pulverizing apparatus, the combination, with the receptacle or pan A, having the circular crushing-channel A and the loose revolving mullers or balls 0, rolling therein, of the rotating tubular shaft B, supporting and carrying the receptacle or pan and having lateral air-channels J, connecting the crushing-channel of the receptacle or pan with the interior of the shaft for conveying the crushed or pulverized material from the receptacle or pan during the rotation of the latter with the tubular shaft, substantially as described.

2. In a crushing or pulverizing machine, the combination, with a receptacle or pan A, having a crushing path or channel A, and mullers or balls 0, moving in the said crushing path or channel, of the rotating tubular shaft B, supporting and carrying the receptacle or pan and having lateral channels J, connecting the crushing path or interior of the receptacle or pan with the tubular shaft, and a suction-pipe I-I, connected with the upper end of the shaft, for drawing off the crushed or pulverized material through the shaft during the operation of the machine, substantially as described.

3. In a crushing or pulverizing machine, the combination of a rotary inclined receptacle or pan A, having a circular crushing path or channel,the revolving mullers or balls 0, moving in the crushing path or channel, the rotary inclined tubular shaft 13, carrying and supporting the receptacle or pan and having lateral channels J, connecting the interior of the receptacle or pan with the inclined tubular shaft, and a suction-pipe H, connected with the tubular shaft for drawing off the crushed or pulverized material through the shaft during the operation of the machine, substantially as described.

4. In acrushin g or p'ulverizing machine, the combination of a receptacle or pan having a crushing path or channel and mullers or balls rolling therein, of a rotary tubular shaft supporting and rotating the receptacle or pan and having lateral air-channels connecting its interior with the receptacle or pan for carrying upward the crushed or pulverized material, and a suction-pipe for creating an upward draft in the shaft, substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.

THOMAS ROVLAND JORDAN.
